Computer images with OpenGL, 4/e is acceptable for junior-to graduate-level classes in laptop graphics.

Assuming no history in special effects, this junior-to graduate-level path provides uncomplicated rules for the layout, use, and knowing of special effects structures and purposes. The authors, specialists of their box, provide an built-in method of two-dimensional and third-dimensional photographs themes. A complete rationalization of the preferred OpenGL programming package deal, in addition to C++ programming examples illustrates functions of many of the features within the OpenGL simple library and the similar GLU and GLUT packages.

Example text

This is an option for specifying a list of values as a pointer to an array, rather than specifying each element of the list explicitly as a parameter argument. A typical example of the use of this option is in specifying xyz coordinate values. Related Libraries In addition to the OpenGL basic (core) library, there are a number of associated libraries for handling special operations. The OpenGL Utility (GLU) provides routines for setting up viewing and projection matrices, describing complex objects with line and polygon approximations, displaying quadrics and B-splines 34 Computer Graphics Software using linear approximations, processing the surface-rendering operations, and other complex tasks.

These routines are prefixed with the letters wgl. The Presentation Manager to OpenGL (PGL) is an interface for the IBM OS/2, which uses the prefix pgl for the library routines. The OpenGL Utility Toolkit (GLUT) provides a library of functions for interacting with any screen-windowing system. The GLUT library functions are prefixed with glut, and this library also contains methods for describing and rendering quadric curves and surfaces. Since GLUT is an interface to other device-specific window systems, we can use it so that our programs will be device-independent.

Basic OpenGL Syntax Function names in the OpenGL basic library (also called the OpenGL core library) are prefixed with gl, and each component word within a function name has its first letter capitalized. The following examples illustrate this naming convention: glBegin, glClear, glCopyPixels, glPolygonMode Certain functions require that one (or more) of their arguments be assigned a symbolic constant specifying, for instance, a parameter name, a value for a parameter, or a particular mode. All such constants begin with the uppercase letters GL.
